a To all whom it may concern:

Be it known-that I, HENRY JAMES LEE, a

subject of the Kin ofGreat Britain, resid-- ompton street, London,

ing at 58 New W. (3., England, have invented a new' and useful Improvement inLockingDevices, (for;

152,064, Feb. 23, 1921,) anddo hereby declare the following to'be a full,clear,"and" exact description of the same.

This invention has reference to a new or improved locking deviceand is particularly adapted for application to automobiles, motor cycles, or other vehicles with the object of preventing the unauthorized use or theft of the vehicle, but the application of the invention is not limited to such use as the locking device could be utilized on bags or trunks, doors or other purposes where locks are necessary. y i

The object of the invention is to produce a simple andelfective locking device which can be generally applied to various purposes as aforesaid, the lock being controlled by a special design of key which is an additional preventive of unauthorized operation of the lock. I

A look constructed according to the present invention will now be described in conjunction with the accompanying drawings, in which Figure 1 is a part'sectional longitudinal elevation through the lock, and'illustr'ates a key for operating same.

Fig. 2 is a cross'sectional elevation on line 2-2 of Fig. 1.

Fig. 3 is a cross sectional elevation on line 3-3 of Fig. 1. n

Referring to the drawings, the lock comprises a tubular sleeve 6 having at the one end a slotted recess 7 adapted to receive the barrel 8 of a key thebarrel of the key being provided with a lug 9 on its periphery adapted to engage with a corresponding slot 7 10 formed in the sleeve 6 of the lock, to define the position at whichthe key can enter and leave the sleeve. The barrel of the key is also provided with a series (in this case six) of pins 11 adapted to engage within 'corresponding apertures 12 formed in a cy'lin-H drical member 13 which is adaptedfor rotation under the control of the key and will be hereinafter termed the rotatable member.

Located in each ofthe slots 12 is a pin 14 slidably'mounted within the slot and having" its inner end in contact with another pin 15 located one withineach slot,16-disposed in the cylindrical member 17 fixed to the outer sleeve 6. The pins l4-and 15 are under the control of the coil springs 18 which are located" at the inner end of the slots 16 and serve to normally maintain the pins at the osition'seen in Fig. l' of the drawings. art 'of'the inner periphery. of the fixed member is formed with a screw thread which is adapted to be engaged by a screw threaded sleeve 19 the said sleeve beingmounted cen trally and slidably on a rectangular extension 20 of a spindle 21 which is axially secured to or formed integral with the rotatable member 13. Formedinthe screwed sleeve 19 is a U-shaped slot 22 which is adapted to receive the cylindrical headed spindle 23 formed at one end of a tongue24 which is adapted for longitudinal motion; the headed spindle 23 of the tongue 24 is maintained in the correct position within the screwed sleeve by means of a coil spring 25 which bears at one end against the said head 28 and at the other end against the end of the rectangular extension 20. The operation of this lock is as follows: When the lock is in I V the position seenin Fig. 1 the rotatable member 13 together with the fixed member 17 are interlocked by means of the pins 15. When it is desired to free the rotatable mem: her from the fixed member the key is inserted in the lock and the pins 11 of the key are pressed against the outer ends of the pins 14 thereby forcing thepins 15 within the slots 16 in the fixed member 17 by this means the member 13 can be. rotated by the key within: the outer sleeve 6; such rotation through the spindle 21 and rectangular extension 20 rotates the screw threaded sleeve 19 within the fixed members 17 and 6,"and longitudinally advances the tongue 24 into locking engagement with a recess or the like in any member which it is desired to lock. Areversal of'the said operation and a withdrawal of the key again unlocks the members 18 and 17 and withdraws the tongue 24 to the unlocking position. p 1

Claims:

1. A locking device having in combination a cylindrical casing, rotary and fixed members co-axially located within said cas-' .ing,a plurality of spring controlled plungers disposed parallel to and around the 1011- gitudinal axis of the said rotary and fixed members, a screw threaded member operable by said rotary member for impartinga, longitudinal movement to the said screw threaded member.

2. A locking device having in combination threaded member slidably mounted on the said spindle from whichit receives its mo tion and rotatable Within said screw threaded sleeve.

3. A locking device having incombination a cylindrical casing, a rotary member coaxially located within said casing and provided with a spindle, a fixed member 00-) axially located within said casing and abutting said rotary member, spring controlled plungers disposed parallel to and around the axis, ofssaid rotary and fixed members, a screw threaded sleeve fixedly mounted in said casing, a screw threaded member slidably mounted on the said spindle from which it receives its motion and rotatable within the said screw threaded sleeve, and a tongue connected to. said screw threaded,

member adapted for reciprocal longitudinal motion on the lock axis. y

4:. A locking device having in combination a cylindrical casing, a locking bolt reciprocable in said casing, rotary and fixed members co-axially located .within said casing, a plurality of spring controlled plungers disposed para'llel to and around the lon-:

gitudinal axis of the said rotary andfixed members, a screw threaded member operable bysaid rotary member for impartinga longitudinal movement to the said locking bolt.

In testimonywhereof, I have signed my.

name to this specification.
